Specification of Letters Patent.

Patented May 5,1914.

Application filed February 13, 1913. Serial No. 748,156.

To all 'zc/0m 'it may concern.'

Be it known that I, SAMUEL P. SANDERS, a citizen of the vUnited States, residing at- Aurora, in the county of Hamilton and State of Nebraska, have invented certain new and useful Improvements in Bellows Suction-Pumps, of which the following is a specification.

This invention relates to pumps and especially to bellows suction` pumps.

The object of the invention is to provide a bellows suction pump of novel and peculiar construction and arrangement of parts, and adapted to be operated by hand or foot pressure.

The invention is specially applicable for purposes of embalming, wherein it is lessential that the pumping operations be made as quickly as possible. Such operations have usually been made by an embalmers assistant, or by the embahner suspending other parts of the embalming work while he perfects such operation preparatory to completing the said process, and such operations are usually accomplished by the use of one or more hand operated devices.

It is, therefore, the purpose of this inven tion to overcome the objections and disadvantages of the devices or apparatus usually employed for aspiration and injection operations, and to furnish a device adapted to be operated by foot pressure of the embalmer for accomplishing such operations, so that he may perfect and cont-rol such operations as desired or as occasion may demand during the use of his hands in performing other operations pertaining to the process of embalming.

With t-hese objects and purposes in view, the invention consists in the novel and peculiar construction and arrangement of parts, as will be hereinafter fully described and pointed out in the claim to follow.

In the accompanying drawings forming part `of this application z-Figure 1 is a side view, the dotted lines showing the device compressed. Fig. 2 is a top view. Fig. 3 is a central vertical section, showing the spring in elevation. Fig. t is an enlarged detail section showing the valve connection. Fig. 5 is a similar view of the valve. Fig. 6 is a sectional elevation showing modifications.

The same reference characters denote the same part-s throughout the several views of the drawings.

According to my invention I provide a blocks of the other pair are of larger diam- 4 eter and constitute the cylinder base 2. The blocks are preferably composed of wood and are glued together and then secured by screw-bolts 3, for strength and durability. To the yperiphery of each of said blocks is secured a flexible material 4 (preferably leather) forming a cylinder, and a cover or outer jacket composed of canvas or cloth 5 is placed around the cylinder.

The means for attaching or securing the cylinder and the jacket to the blocks consists of af metallic band 6, for each pair Of blocks. The blocks preferably-have an annular shallow groove 7, over which'the said materials are placed and the bands are placed into position opposite said grooves where they are secured by screws 8, the said attachment being such as to make the connections perfectly air-tight. The head 1 is provided with a met-al face plate 9, and the base 2 has a. similar plate 10, upon its outer face. The inner face of the head and the inner face of the base are each provided with a metal plate 11 and 1la respectively having an annular lia-nge 12, and these plates form bearings for a spiral spring 13. All of said plates being secured by the bolts 3, so that the head and the base may have unusual strength and durability, and so that the spring may have strong abutment-s without injuring the head and the base.

The base 2 is provided with a vertical duct or port 14, extending from the inner face of the base into the body of the base, and an orifice 15 extends froml the port 14 through the periphery of the base, and the plate 11a has an aperture 16 opposite the port 14. A two-way valve 17 has a ystem 18 secured in the orifice 15 and is provided with a pair of nipples 19, for attaching suitable hose 20.

In arranging the leather and the cloth or canvas preparatory to applying the same to the blocks, they are laid one upon the other and placed in cylindrical position so that their meeting edges over-lap, and such edges are preferably glued or cemented, and seWed or stitched together, and slipped on the head and the base While the spring is in expanded position, and secured by means of the bands, the valve is then attached.

'The hose is applied to one of the valve nipples for eject-ion of gas and fluid from a corpse, and to the other nipple for injection of embalming.

Referring to the modification shown in Fig. 6 the head 21 and base 2Q are of metal, and t-he annular flanges 23 thereof are of such thickness and depth as to form rigid rims and guides for a spring 22a. A thin metal band 2li is secured to the rims by screws 25 for clamping the leather E26 and the cloth 27 to the rims. lThe rim of the base 22 is provided With an aperture 28 for attaching' a tivo-Way valve.

The device is of such size and arrangement as to be readily operated by foot pressure of the embalmer on the head l, preparatory to or during the process of embalming so that the hands of the embalmer are free for other Work, and an assistant is not required for this purpose.

lt is obvious that the embalmer is able to control and to exactly and quickly measure the amount of pressure he needs at various times in an embalming operation. Without removing his foot from the head of the de vice.

I do not Wish to confine myself to any particular materials employed in the manufacture of this device, nor to any particular size or shape of the device, but reserve the right to make such changes and variations therein as may come Within the scope of the claim.

Having thus described my invention what I claim as new and desire to secure by Letters Fatent is n a bellows suction pump, the combina-V tion with a double head, a double base, an outer casing composed of fabric material, an inner casing composed of flexible mate rial, and means for securing` the casings to the head and the base, of a pair of plates havingan annular flange one plate being secured to the inner face of the head and the outer plate being secured to the inner face of the base, bolt-s extending through the head, the base and the plates, and a spiral spring abutting against the plates and Working' Within the flanges for operating the casings. l

In testimony whereof l aflix my signature in presence of tvvo Witnesses.
